Question

Answer

Basophils of white blood cells are connected with the release of histamine and the natural anticoagulant heparin. Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues. They can be found in unusually high numbers at sites of ectoparasite infection.

So, correct answer is 'Basophils'.

Answer

The type of white blood cells is concerned with the release of histamine and the natural anticoagulant heparin are Basophils. They contain granules filled with histamine, When basophils encounter allergens they release histamine. Histamine increases blood flow to damaged tissues, resulting in swelling and inflammation. Basophils also contain anticoagulant heparin, which prevents blood from clotting too quickly.
So, the correct answer is 'Basophils'.

Answer

Answer

The correct answer is option 'C' - Basophils.

Basophils are a type of white blood cell that is responsible for releasing histamine and heparin. They are granulocytes, which means they have granules in their cytoplasm that contain various chemical substances.

Function of Basophils:
Basophils play a crucial role in the immune response and are involved in both innate and adaptive immunity. They are primarily responsible for allergic reactions and respond to allergens by releasing histamine. Histamine is a chemical messenger that causes vasodilation and increased permeability of blood vessels, leading to the characteristic symptoms of an allergic response such as itching, swelling, and redness.

Heparin:
Heparin is a natural anticoagulant that prevents blood from clotting. It works by inhibiting the activity of certain clotting factors in the blood. Basophils release heparin to prevent blood clotting around the site of an allergic reaction, ensuring that immune cells can easily reach the affected area.

Appearance and Characteristics:
Basophils are the least common type of white blood cells and make up only a small percentage of the total white blood cell count. They have a lobed nucleus and large granules that stain dark blue-purple with basic dyes, such as methylene blue. These granules contain histamine, heparin, and other inflammatory mediators.

Role in Inflammation:
In addition to their role in allergic reactions, basophils also play a role in inflammation. When tissues are damaged or infected, basophils migrate to the affected area and release their granules, which contain various inflammatory chemicals. These chemicals recruit other immune cells to the site of infection or injury and promote the inflammatory response.

In summary, basophils are a type of white blood cell that releases histamine and heparin. They are involved in allergic reactions, inflammation, and immune response. Histamine causes vasodilation and increased vascular permeability, while heparin prevents blood clotting.
